Traffic 'Calming'

Traffic what?

Can anyone [excepting those who design them] explain how 'the powers that be' can have the audacity to call chicanes traffic 'calming' measures?

They could be termed a young male drivers free rally course.

They could be termed a road rage hazard.

They could be cited as a major cause for increased insurance premiums.

They could easily be cited as one of the main reasons for increased fuel consumption, and therefore as 'anti-green'.

But traffic 'calming' NEVER!
